BINDING-SPREADER.

Patented Dec. 9, 1919.

Application filed March 1, 1919. Serial No. 280,158.

To all whom it may concern:

Be it known that I, EDWARD F. KowALs'KI, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Binding-Spreaders, and declare the following to be a full, clear, and exact description of the same, such as will enableothers skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of thisspecification.

This invention relates to a tool for handling leather or similar beading, and has for its object an improved device adapted to hold the corded or ridged parts over the central portion of the web in spread apart position, while tacks or similar holding means are being driven through the central web portion, so that, when the driving of the tacks is finished, these corded portions practically meet thereover. My device makes it possible to not only hold the beaded portions wide enough apart to permit this, but to move rapidly along the strip of heading Without readjustment; thus one operator can easily and rapidly handle not only the tool but the hammer or mallet by which the tacks are driven.

In the drawings:

Figure 1 is a perspective of my improved device in working position relatively to a strip of beading, part of which is shown already attached, part in spread position ready for nailing, and part not yet reached for such operation.

Fig. 2 is an enlarged cross-sectional view of a strip of beading as it is furnished in strips or rolls.

Fig. 3 is a similar cross-sectional view showing the beading portions spread apart toward and over the edge portions of the web, and with the claws of the tool in position between them.

Fig. 4; is a view similar to Fig. 2, but showing the holding tacks driven through the web, over which the beads have resumed their normal osition.

. Fig. 5 is a perspective of the under side of the clawed or tip portion of the tool, showing its contour which acts to successively spread the ridged portions as it is moved along the strip or beading. V

A indicates the handle portion of the tool, near whose forward end is a rectangular hole B, preferably with sloped or beveled edge portions, through which slidably passes the heading C, which consists of a web portion D and beaded portions E, which, before the strip of beading has been acted upon, as well as after the driving of nails therethrough, nearly or actually meet over the central portion F of the web.

The operative or working end of the tool is formed with a pair of spreading claws or tips G, the outer faces of which are preferablygrooved slightly, in order to secure a neater and closer engagement of the ribs thereagainstr The under portion of the tool tapers from the extreme width of the claws toward the point J, so that when the tool is first inserted in the end of the beading strip the pointed end can be easily forced into position between the two beads E. Throughout the length of the strip, this wedge point J sllghtly precedes the claw members G between the beads, and spreads them in advance for the successive contact of the claw members G.

As soon as the claw portion of the tool has been moved far enough on the beading, for example an inch or two, to permit the nailing operation to begin, this end of the beading is held up against the base or article, as for example the upholstered edge of a vehicle seat, and a tack L driven into the web D. The tool is then drawn along the beading until the desired point in the web for another holding tack has been exposed and slightly passed by the action of claws G upon the beads E; by the time two or three tacks have been driven, that portion of the beads E adjacent the first driven tack has been so far separated from the spreading influence of the claws G that they tend to resume their normal position of almost if not entirely over-engaging the web portion D, through which the tacks have been driven. 1

What I claim is:

1. In a device of the character described, in combination with a handle portion having a guide aperture for the slidable engagement of a strip of beading therethrough, a bifurcated end portion having its under face tapered to engage and spread the individual beads constituting the upper portion of such stri 2. A leather handling tool, having one end formed to wedge apart the beaded portions of a finishing strip and to slidably engage the opposing inner edge portions of said head portions to facilitate access to the con tral web of the strip, a suitably remote portion of said tool being formed as a guide for that portion of the strip not yet reached by the operative end of the tool.

3. In a leather handling tool, in combination with a handle portion provided with means for guiding a beaded strip of material toward the operative end thereof, a bifurcated end portion whose members are adapted to slidably engage the adjacent inner faces of the beaded portions to spread them for the exposure of the central Web of the material.

4:. In combination with means for guiding a strip of beaded material, a bifurcated spreading element whose members are adapted to be interposed between the normally adjacent beaded portions of the strip to force them apart to permit temporary access to the central web of the strip.

5. A binding spreader, comprising a ban dle portion adapted to serve also as a guide for the strip to be acted upon, and an end portion adapted to be inserted between the beads on the strip for temporarily forcing them apart to effect the exposure of the central Web portion.

6. In a spreader for fabricated binding, the combination, with a handle portion part of which is adapted to serve as a guide for the binding strip, of an end portion whose lateral faces are formed to slidably engage the adjacent edge portions of the beads on said strip which normally overengage the web portion, thereby temporarily exposing successive portions thereof.

In testimony whereof I sign this specification in the presence of two witnesses.
